"An eminently readable and very fruitful study." - Jonathan Sperber, University of Missouri (Catholic Historical Review) "The work offers readers new, engaging ways of thinking about German Catholicism in the nineteenth and twentieth centuries and provides a glimpse into the world of everyday German Catholics and their attempts to navigate the practice of their religious faith in the modern world." - Beth Griech-Polelle, Pacific Lutheran University (German Studies Review) "Offering a tightly bounded history of Catholic pilgrimages to Trier and Aachen, Skye Doney has ably foregrounded how Catholicism in Germany, both as an institutional religion and as a mass movement of millions, sought to straddle faith and empirically-based science." - Matthew P. Fitzpatrick, Flinders University (Journal of Religious History) "An important study that broadens our understanding of Catholic faith and practice in the nineteenth and twentieth centuries." - Kevin P.
